You'll find goolge is amazing. Especially because it gives you the number of hits letting you compare how common different expressions are or find out if people actually say things. It takes some practice though because you have to learn not only what to search for but how to interpret the results that come up. And of course there are no English translations. (most of the time)

I actually tried that before, but I'm at such a beginner's level that I can't analyse the results or figure out if the phrases are what I think they meant.

anyway I just tried to seach for this phrase 大ファンから信じて待つ (which I am not sure if it is gramatically correct or even mean what I think it means), and it came up with 990 results but none for the entire phrase. Is that very clear that there is something wrong with the phrase? This is the entire sentence - 活動休止のでライブを今も将来も多分見られませんとおもいますが大ファンから信じて待つ!
